Middle relay
by Tora Tora Tora 05 Feb '14

05 Feb '14

I am trying to run a middle relay with no-exit policy. It was my assumption that a middle relay would only communicate with other relays on 9001 port. Yet I see my relay IP address attempting connections to other IP address on ports that are non-9001 (or 9030).

Full mail headers attached. I read Jurre's analysis, but I disagree. I could be mixing this up with something else, but if I recall correctly, that screensaver Trojan Horse trick was one method by which the government was de-anonymizing Tor users, though I don't recall the exact name of this attack vector. Your IP of your relay is public of course, but if you opened that a location/identity that you wanted to stay hidden, in my opinion I would consider that to be compromised. Thanks for the report.

Ubuntu is killing tor when getting low memory
by toxi roxi 02 Feb '14

02 Feb '14

Hi Folks, im running many relays which are doing a nice job. But i have also some smaller relays outside which have just 256mb. They are performing quite quell - but on one relay im facing issues which i think you may help me. this relay seems to ran out of memory from time to time (2 to 5 days) and i found out via dmesg, that ubuntu itself is killing the process to free up memory. the swap is used, but far away from full. as this stops tor immediately its bit annoying that i need to restart the releay without any reason. is there any way to tell ubuntu or to prevent that the tor process is killed for freeing up memory? i dont care about other processes as this machine is for tor purposes only. thanks for your expertise! Geri

You should learn how to > use 'service reload' rather than 'service restart'. :) No, I don't have AccountingMax enabled, which is one of the reasons why I was puzzled by the hibernation flag. Thanks for the tips on the service, I should have known better. I was restarting often because I was making adjustments to the DirPort and the hosted webpage (that .png thumbnail never loaded when it was offered locally, so I just linked to the hosted one on torproject.org) and it took a few tries before things were working right. Well, at least I won't be restarting Tor frequently going forward. Thanks. >> 3) There are mysterious warnings in the log: >> >> Jan 30 23:07:29.000 [warn] EXTEND cell received, but not via >> RELAY_EARLY. Dropping.

Yes, I had ProtocolWarnings enabled, good eyes there. I had it on because I thought that it would help me see Tor-level security threats, but I think it's better with it off at least for now. Thanks for the help. Jesse

Thanks again guys for the help. "usuexit" is now online, and should be functioning properly, but there seem to be a few mystifying issues: 1) TorStatus marks it as "hibernating" which it clearly isn't; it's online and accepting connections. I'm not sure what made TorStatus think it was offline. 2) For the first nine hours it has moved about 12 MB of data. I would think it would be more than that, especially for an exit. There's a blog post outlining the growth rate for guards, but how about for exits? 3) There are mysterious warnings in the log: Jan 30 21:57:36.000 [notice] Circuit handshake stats since last time: 0/0 TAP, 50/50 NTor. Jan 30 22:57:36.000 [notice] Circuit handshake stats since last time: 0/0 TAP, 31/31 NTor. Jan 30 23:07:29.000 [warn] EXTEND cell received, but not via RELAY_EARLY. Dropping. [4 similar message(s) suppressed in last 3600 seconds] Jan 30 23:07:29.000 [warn] (We have dropped 95.24% of all EXTEND cells for this reason) Jan 30 23:57:36.000 [notice] Circuit handshake stats since last time: 0/0 TAP, 39/39 NTor. Jan 31 00:01:41.000 [warn] Got headers "HEAD / HTTP/1.0\r\n\r\n" with unknown command. Closing. Jan 31 00:57:36.000 [notice] Circuit handshake stats since last time: 2/2 TAP, 41/41 NTor. Jan 31 01:04:46.000 [warn] EXTEND cell received, but not via RELAY_EARLY. Dropping. Jan 31 01:04:46.000 [warn] (We have dropped 95.45% of all EXTEND cells for this reason) I'm familiar with the meaning of the "EXTEND" cell, but I'm not sure what RELAY_EARLY is, nor do I know what this warning means. If the relay has an exit policy, why are circuits being extended beyond it? Hidden services, maybe? Basically the log has more warnings in it than it should (at least based on my experience with regular relays) and I'm not sure why. I tried restarting Tor, but the warnings still appeared. Any ideas on what I can do about them, if anything? Thanks, Jesse

Using syslog for monitoring bridges
by Andreas Fritzel 30 Jan '14

30 Jan '14

Hey all, In two different countries I run 3 Tor bridges for a while now. For monitoring, I want to quit using the local filesystem for storing files, filled by syslog and be able to store the syslog info on a remote system. This is done easily with rsyslog[1], but I want to store it at home without the link between the three bridges and my home IP. So, I was thinking about sending it with rsyslog over TCP to a Tor Hidden Service. Is there anyone who can help me out with this? I was thinking about using SOCKS, but it didn't work out :(.
